“An excessive heat warning means that a prolonged period of dangerously hot temperatures and high humidity will combine to create a dangerous situation in which heat illnesses are likely,” states the National Weather Service bulletin.

Relief from the airmass may come as early as Thursday, with rain and thunderstorms predicted, but the bulletin states that by Friday and on through the weekend, the heat should be decreased significantly.

Throughout the next few days, local officials are asking citizens to monitor their health and take all necessary precautions. All of them urge everyone to stay hydrated.
